HOME HISTORY BIOLOGY CONSERVATION ... LINKS You Otter Know the Difference When is an otter in the sea not a sea otter? When it’s a river otter of course. River otter skeleton Sea otter skeleton It’s a common mistake to confuse sea otters with their cousins the river otter because river otters live around either freshwater or the ocean. In fact, there are so many river otters around our seashores, and they are so active in the sea, that people are easily convinced the otter they see is the sea otter. But once you know what to look for, you’ll easily tell river and sea otters apart. Can you tell which is which? If you see an otter moving easily on land then it’s a river otter. Long legs make walking easy and they frequently move to and from their dens in the forest, or playfully slide down their otter runs into the sea. Sea otters are true ocean-dwelling marine mammals, almost never coming out of their ocean home. They are really quite clumsy on land and are perfectly capable of spending their entire lives out at sea. Seeing an otter in the water is one of the best ways to identify it. At the surface, river otters swim belly-down and expose very little of their back, while sea otters swim belly-up and float high in the water due to their air-filled fur.

The river (or land) otter is found throughout Alaska with the exception of the Aleutian Islands, the offshore islands of the Bering Sea, and the area adjacent to the arctic coast east of Point Lay. River otters, or other otter species, inhabit most of the rest of the world. All are amphibious members of the family Mustelidae along with mink and sea otter. Animals in this family produce a strong, sometimes disagreeable scent, which is discharged from a pair of anal glands. General description: The North American river otter is a thickset mammal with short legs, a neck no smaller than its head, inconspicuous ears, and a muscular body that is broadest at the hips. Its tail is powerful and a little more than a third as long as its head and body. Only the hind feet are webbed. Adults weigh 15 to 35 pounds (6.8-15 kg) and are 40 to 60 inches (102-152 cm) in length. On the average, females are about 25 percent smaller than males. When prime, river otter fur appears black-brown, with the belly slightly lighter in color than its back. The chin and throat are grayish. Otter fur consists of a very dense undercoat overlaid with longer guard hairs, which are usually removed by furriers.

Otters are mammals of the weasel family. There are two distinct species of otters in BC: river otters (Lutra canadensis) and sea otters (Enhydra lutris). River otters are sleek, usually weigh no more than 14 kg, and have a tail that is about 2/3 the length of their body. They live in dens in riverbanks or shorelines and forage along the shore and in the water. Sea otters are larger, weigh up to 45 kg and measure up to 148 cm including their tail, which is about 1/3 the length of their body. They spend most of their time in the ocean. Sea otters are not found in the harbours of the Capital Region, while river otters are fairly common. Where do otters live?

Otters spend a large amount of their lives in water. © Lee Brun Otters, Inside and Out All otters seek most or all of their food in water, and they've had a long time to adapt to this way of life. Their first distinctly aquatic ancestor dates back 30 million years, according to the fossil record, which shows that ancestors of the North American river otter ( Lontra Canadensis )crossed the Bering Land Bridge and arrived in North America by the Upper Pliocene epoch. The earliest otters had sharp cutting teeth, which suggests that they were first attracted to water by fish rather than by hard-shelled invertebrates like crabs and crayfish. In this regard, river otters resemble these ancestors more closely than do other kinds of otters of 16

CURRENT STATUS Legal Status The otter is listed on Appendix 1 of CITES, Appendix II of the Bern Convention and Annexes II and IV of the Habitats Directive. It is protected under schedule 5 of the Wildlife and Countryside Act 1981 (as amended) and Schedule 2 of the Conservation (Natural Habitats, etc) Regulations, 1994 (Regulation 28). Conservation status The European sub-species is listed as globally threatened on the IUCN/WCMC Red Data List. The species appears on the UK Biodiversity Steering Group (1995) short list. National status The Otter is listed as a Priority Species by the UK Biodiversity Group.The National Otter Survey undertaken in 1977-79 showed that otters were present on 170 of sites surveyed out of a total of 2940 sites - 5.78% (Lenton et al, 1980). By the 2000-02 survey otter evidence was found on 1137 out of 3327 sites - 34% (Crawford 2003). Surrey Status The Otter was selected by the Surrey Biodiversity Partnership to be on the mammal short list (Surrey Biodiversity Partnership (1999).Until recently, otters were completely absent from Surrey apart from the odd, casual visit on the River Wey catchment. None of the sites surveyed in any of the national surveys has ever had signs of otters. Regular spot checks at the national sites in Surrey had not shown any otter evidence until 2003.In 2003 otter evidence was found over a period of six months on the North Wey catchment. One dead animal was found on the River Blackwater in 2004 and fresh spraint (droppings) in 2005 (see 3.1 below).

Shooting Damage Prevention and Control Methods The North American river otter, Lutra canadensis Because river otter damage has been minor compared to that of other spectral research and experimentation has been done. Registration of repellents, toxicants, or fumigants for river otter control has not been sought. Alternate aquacultural practices and species, predator avoidance behavior, and use of protective habitat have not been fully explored. Careful assessment should be made of reported damage to determine if non lethal preventative measures can be employed, and to ensure that if any lethal corrective measures are employed, they do not violate state or federal laws. Damage problems should then be approached on an individual basis. Cultural methods and habitat modification are normally not applicable. Opportunities to use repellents, toxicants, fumigants, and frightening devices are infrequent, yet the development of any of these or other effective non lethal approaches would be preferable to lethal control measures.

River otters make up the subfamily Lutrinae, of which there are 13 recognized species in four genera. D. Genus, speciesLutra canadensis There are eight species in the genus Lutra. Species can be distinguished by the shape and size of the hairy patch on the nose pad. E. Fossil records The first aquatic otter appears in the fossil record 30 million years ago. Another species, Paralutra jaegeri, lived 25 million years ago and may have been an ancestral form of modern river otters. River Otter Habitat and Distribution Historically, North American river otters were widely distributed throughout Alaska, Canada, and the contiguous United States. Due to fur trapping and hunting, by the nineteenth and twentieth centuries river otter populations were greatly reduced throughout the lower 48 states except in the northwest, the upper great lakes region, New York, New England, and the states along the Atlantic and Gulf coasts.

Asian short-clawed otter. Photo D. Scott There are around 13 different species of otter around the world. Estimates of species numbers vary because there are some species which may now be extinct and others which have not been proven to be genetically separate species. Otters in the UK In the 1950's, otters were considered to be widespread in Britain and Sussex. From the 1960's onwards their numbers crashed, mainly due to industrial and agricultural pollution and particularly the chemicals Dieldrin and Aldrin. They became extinct in many parts of the UK including Sussex. The UK population is making a comeback from its 1950's decline but it is estimated that it will take at least 50 years before it recovers to its former widespread status Click here to view make of national distribution (National Biodiversity Network UK) Legal protection international The otter is listed in Annexes II & IV of the EC Habitats Directive (EC/92/43), Annexe II of the Bern Convention and Appendix 1 of CITES. It is classified as "vulnerable" by the IUCN.
